Flmodafinil (2-[bis(4-fluorophenyl)methylsulfinyl]acetamide) is the bis(4-fluorinated) structural analogue of modafinil, also known as bisfluoromodafinil or lauflumide, studied primarily as a reference compound in analytical chemistry and sports drug testing. CAS 90280-13-0; molecular formula C15H13F2NO2S; molecular weight 309.3 g/mol. Supplied encapsulated; purity specification pending batch COA. For laboratory research use only; not for human or veterinary use.
Two fluorine atoms separate it from one of the most studied wakefulness compounds in the literature, and almost everything else about it is unstudied. Flmodafinil (CRL-40,940) sits in a research position that is unusual and worth stating plainly: its parent structure carries thousands of published records, while the analogue itself carries a handful. We supply it as an analytical reference material and describe the evidence exactly as thin as it is.
A fluorinated analogue of modafinil. Flmodafinil belongs to the eugeroic series developed at Laboratoire L. Lafon alongside modafinil (CRL-40,476) and adrafinil, and differs from modafinil by para-fluorination of both phenyl rings. Its close relative fladrafinil (CRL-40,941) is the corresponding N-hydroxy compound, which the published record describes as a prodrug converting to flmodafinil (Krug et al., 2026).
Identity is the practical problem in this family. CRL-40,940 and CRL-40,941 differ by a single oxygen atom, carry adjacent development codes and are routinely interchanged across supplier catalogues. Flmodafinil is C15H13F2NO2S at 309.3 g/mol (CAS 90280-13-0); fladrafinil is C15H13F2NO3S at 325.3 g/mol (CAS 90212-80-9). Laboratories should confirm identity against their own analytical data rather than against a product name.
What the research explores. The published work on this compound is small and is concentrated in analytical chemistry rather than pharmacology:
The work described here is analytical and characterises the compound's behaviour in laboratory systems; it does not establish efficacy or safety in humans, and no controlled clinical literature exists for this analogue. Full citations are listed under the Scientific References tab.

Flmodafinil (CRL-40,940) is the bis(4-fluorinated) structural analogue of modafinil, systematically 2-[bis(4-fluorophenyl)methylsulfinyl]acetamide (CAS 90280-13-0), also called bisfluoromodafinil or lauflumide. Condor Research supplies it strictly as a Research Use Only reference compound for analytical and in vitro work, not as a medicine, supplement or product for human or veterinary use.
They are distinct compounds with adjacent development codes and are frequently interchanged in supplier catalogues. Flmodafinil (CRL-40,940) is the bis-fluorinated acetamide, C15H13F2NO2S at 309.3 g/mol. Fladrafinil (CRL-40,941) is the corresponding N-hydroxy compound, C15H13F2NO3S at 325.3 g/mol, which the literature describes as a prodrug converting to flmodafinil. This listing is CRL-40,940.
Flmodafinil is modafinil with both phenyl rings para-fluorinated; modafinil (CRL-40,476) is the unsubstituted parent at C15H15NO2S and 273.4 g/mol. The two differ by two fluorine atoms, but not in the weight of evidence behind them: a PubMed name search in September 2026 returned 2,416 records for modafinil and one for flmodafinil. The modafinil literature should not be assumed to transfer.
All three belong to the eugeroic series developed at Laboratoire L. Lafon. Adrafinil is the oldest of the group and the only one with a former medicinal authorisation in Europe, whereas flmodafinil and fladrafinil are later fluorinated analogues that were never developed to authorisation. All are supplied here only as research reference compounds.
Flmodafinil is not an authorised medicinal product in the European Union or elsewhere, and it is not a scheduled narcotic or psychotropic substance in the EU. National rules differ, and some jurisdictions regulate psychoactive substances by effect rather than by list. Purchasers are responsible for confirming the status of this compound in their own jurisdiction before ordering; eligibility is assessed per destination and orders may be declined.
The capsule is a pre-weighed solid format that makes a fixed 50mg quantity of reference compound easy to store and handle in the laboratory without repeated weighing. The stated figure is an analytical reference quantity (mass per unit) for characterisation and identification. It is not a dose, serving or intake, and the format does not imply suitability for ingestion or any physiological application. Supply conditions are set out in clause 3 of our Terms and Conditions.
No. Each capsule already contains pre-weighed solid compound, so no reconstitution is required for laboratory handling.
Each bottle contains 60 HPMC (vegan) capsules, with each capsule providing 50mg of flmodafinil as an analytical reference quantity. The purity specification is pending batch testing and is not stated on the label until the Certificate of Analysis exists.
Flmodafinil has the molecular formula C15H13F2NO2S, a molecular weight of 309.33 g/mol, and CAS number 90280-13-0. Its IUPAC name is 2-[bis(4-fluorophenyl)methylsulfinyl]acetamide. These identity figures correspond to PubChem CID 13271852.
Not yet. This compound has no batch in stock and therefore no Certificate of Analysis. We state that rather than carrying a purity claim the testing does not yet support: the product label shows the purity field as pending, and the COA will be published alongside the batch when it is tested.
Yes. Flmodafinil and fladrafinil fall under World Anti-Doping Agency class S6 (stimulants) and are prohibited in competition. That status underpins the principal documented research requirement for this material: reference standards for doping-control method development, metabolite identification and confirmatory analysis.
Condor Research supplies Flmodafinil Capsules directly, dispatched from our EU facility in Slovakia to eligible destinations, so intra-EU orders avoid third-country customs handling. Supply is restricted to verified professional research purchasers and eligibility is assessed per destination.
